Shelly 1pm with push button for automation triggers only?

Hi There,

I have a couple of spare Shelly 1pms and trying to wire it to a push button switch - what I would like to achieve is just simply a smart button. So there would be no light or anything behind the Shelly, I just want to be able to press the button and then use the button press as a trigger.

Could anyone push me in the right direction to get me going on this?

Thanks!
